Sweeney described the contestants' return as "exhilarating" and congratulated Britt, though she added that her "favorite moment" was watching former participant Cassandra Sturos.

"Her smile on the scale and the way this show changed her life is exactly what The Biggest Loser is all about," Sweeney said. "Regardless of the gameplay, I always am proud of this show because it transforms lives and inspires others to change their lives."

She added: "Hopefully you'll tune in for next week's live finale to see how it all turns out. I for one was shocked and thrilled to see how far everyone had come when we shot that episode two months ago. I am very much looking forward to how amazing they will look next week!"
